Linker Script: Put object files at specific addresses into ELF file

Linker Script: Put object files at specific addresses into ELF file

[Khronis Official]

Hello,

I have two files `one.c` and `two.c` which respectively contains `f_one`
and `f_two` functions. After compilation, I obtain two object files `one.o`
and `two.o`. I would like to place each object file (function) at
particular addresses (absolute) in the resulting binary.

For now, I succeeded in placing the two object files with a relative offset
in the final ELF by specifying the addresses in the `.text` section with a
linker script.

Linker script used to compile `one.c` (`objects_one.lds`):

    [...]
    .text 0 :
      {
         . = 0x10000;
        *(.text .stub)
        /* .gnu.warning sections are handled specially by elf32.em.  */
        *(.gnu.warning)
      }
    [...]

Linker script used to compile `two.c` (`objects_two.lds`):

    [...]
    .text 0 :
      {
         . = 0x40000;
        *(.text .stub)
        /* .gnu.warning sections are handled specially by elf32.em.  */
        *(.gnu.warning)
      }
    [...]

After analysing the final binary with objdump, I got:

    [...]
    0000000000010000 <f_one>:
    0000000000050014 <f_two>: // relative to f_one (0x40000 + 0x10000 +
size of `f_one`)
    [...]

My issue is that the function `f_two` starts at address `0x50014` (which is
a relative position from the first function and thus from the first object
file) and not at address `0x40000`.

I would like to have the following with objdump:

    [...]
    0000000000010000 <f_one>:
    0000000000040000 <f_two>: // absolute address
    [...]

Is it possible to do it with GCC?

Note: for the last linking, I do not specify a linker script.

Best Regard,

K.
